AUTOMATIC ACCELERATOR.

Application filed July 29,

This invention relates .to a device to be used for automaticallyaccelerating the supply of gasolene to the carbureter of an automobileengine without the use of the cus- 6 tomary foot accelerator pedal, andit has reference to a device which comes automati- .cally into playwhile changing the gears.

A device of this class is particularly advantageous when driving inheavy trafic and 1 in places where extra precaution is essential.

It furnishes an even smooth acceleration,

permitting the driver to keep one foot on the clutch and the other oneon the brake insures smooth operation in either forward or backwardmotion and practically eliminates objectionable noise caused by racingof the motor, such as is now the case with the present acceleratorarrangement.

The device is clearly advantageous in that it overcomes injuriousdepreciation of parts caused by racing motors particularly. whenchanging from high to low onsteep grades. It thereby effects anoticeable saving in fuel.

The particular details and their relative arrangement and associationwill become morereadily apparent from the following description anddrawings In the drawings V Figure 1 is a view in section and elevationz: 1 of one embodiment of the invention showing the complete structure.I

the clutch, said control coming into play and shifting the gears andoperating the clutch in a customary manner.

Attention is first invited to Figures 1 and 2 wherein it will be seenthat the reference character 6 designates generally the shank of aclutch pedal extending through the openmg in a floorboard 7. This shankcarries a special clamp 8 with which a push rod 9 is connected at oneend. The push rod is connected at its opposite end with an upstand ingportion 10 on a swingably mounted U- shaped carrier 11. Incidentally,this carrier is located within a suitably shaped housing 12 and the armsthereof are connected with an adjustable pivot forming shaft 13. Asshown, the carrier constitutes a mounting for va'spring-pressed latch14. The latch is cooperable with a shoulder 15 formed on a se mentalplate 16carried by a tubular shaft 1 The tubular shaft extendstransversely across the housing 12 and is fastened by set screws orequivalent means to a rock shaft 18. On the left hand end of the rockshaft in Figure 2 is a crank arm 19 which serves a purpose to behereinafter described. On the opposite end is a short arm 20 with whicha return 1 spring 21 is connected.

, Attention is here invited to a gauge element 22 having a stop lug 23on its inner pivoted end for cooperation with a complemental lug 24 onthe tubular shaft 17. These lugs cooperate in limiting the rotation ofthe shaft 17 in one direction. This element 22 is formed with aupointer25 cooperating with a scale 26 in order to indicate accurately theadjustment of the stop lugs; A retaining nut 26 is provided for thiselement, thereby permitting it to be held in any suitable ad-' justedposition. r Attention is now invited to a bracket 27 which is rigidlyfastened to the floor board. On the end portion of this bracket is apivotally mounted bellcrank 28 carrying an anti- .friction roller 29 forcooperation with a cam 30 on an adjustable abutment or bracket 31carried by the fuel control rod 32 leading tetheearbureter 1 1101;shewu).- Connected 10o to the bellcrank through the medium of a shortlink 33 is an actuator 33% of the design indicated. This is alsopivotally mounted on the bracket 27 and the one arm thereof is connectedwith a rod 35 which is in turn connected with the aforesaid crank arm19. It is yet to be stated that suitable attaching brackets 36 areconnected with the aforesaid housing 12, whereby to permit the latter tobe mounted on the motor or chassis as desired.

\Vith this arrangement it is obvious that when the clutch pedal ispushed down to release the clutch, the pushrod 9 is moved in a directionfrom right to left as indicated by the arrow. This swings the U-shapedmember 11 upon its pivot in a corresponding direction, thus bringing thelatch 1l- 1n the position to drop behind the shoulder 15 on thesegmental plate 16. Now, when the foot is removed from the clutch pedalto allow the clutch toibe thrown in, the latch being engaged in theshoulder 15, serves to rock the shaft 17 as well as the shaft 18. Thisproduces an actuation of the abutment 31 and carbureter control 32through the medium of the shankarm 19, part 35, 3a, and the bellcrank28. At a predetermined time in this return of the clutch, the latch 14clears the shoulder 15 owing to the eccentricity of the pivot 13 ascompared to the axis of rotation of the shaft 17.

Referring now to Figures 8 to 5 inclusive, it will be seen that thereference character 37 represents a carbureter having a suitableactuator '38. Cooperating with this part 38 is abracket 39 carrying ananti-friction roller 40. The bracket is mounted on a slide 41 which ismovable through a bore in a guide bloc 42. A push rod 13 is connectedwith its slide at one end, and at its opposite end is connected with acrank arm 44. The crank arm, as shown in Figure 1, is fastened upon theextendmgend of a small rock shaft 4-5 which is journaled for oscillationin a gear casing 46. A suitable attaching bracket is provided for thiscasing. Keyed or otherwise fixedly mounted on the rock shaft 45 is abevelled gear l7 which cooperates with a bevelled pinion d8. The pinion41-8 is car ried by airoscillatory shaft 49 which, as

shown in Figure 3 extends atiright angles to the push rod 4-3 and iscoupled as at 50 witha short rock shaft 51 in an appropriate enclosure52. The rockshaft 51 is provided witha rocker arm to which a push andpull link 54: is connected. This linkin turn is connected with theclutch pedal represented generally at 55. 1

IViththis arrangement it is obvious that when the clutch pedalis-operated, the link 54; serves to actuate the rocker arm This in'turnoscillates the shaft 49 which, through the medium of the intermeshinggearing 4:7 and 48, operates the push rod 43. Thus, the
